In this project, we will build an IoT-based AC Electricity Energy Meter with an ESP32 Microcontroller & HMI Display. The energy meter shows the real-time value of RMS Voltage, Current, Power, and Power Factor. It also shows the value of Total Energy consumption in kWh as well as Electricity cost in dollars ($). For visualization, we have used a 7-inch HMI Display from DWIN Technology. To monitor the Energy Meter parameter remotely, we upload the Energy Meter data on the Blynk dashboard every 5 seconds.

We can use a current sensor (SCT-013) and voltage sensor (ZMPT101B) to build an AC Energy Meter. Earlier we built an IoT Smart Energy Meter using ESP32 & Blynk which could only send voltage, current, power, and KWh data to Blynk. However, the energy meter was missing some important parameters like cost calculation and HMI Display Data visualization.

This IoT AC Energy Meter does the following tasks:

1. Utilizes a 7-inch HMI Display to visualize the voltage, Current, Power, Power Factor, Energy Consumption & Cost.
2. Connects the ESP32 to the internet via WiFi and uploads the Energy Meter Data to the Blynk Server
3. Calculates the estimated cost of electricity consumed based on a predefined cost per kWh, allowing the user to monitor electricity expenses.
4. Uses the EEPROM to store and retrieve the cumulative energy consumption (in kWh) across power cycles, ensuring the persistence of data.
5. Features functionality for controlling a Load both from the Blynk app and through HMI Display.

[rauhan]

Excellent tutorial, well explained, thank you very much for your contribution :)

[rylegaming]

hello I can also want to research about that and your idea is super good, but the question is how I can estimate the cost if every appliances is different cost per kwh. I hope uou will answer my question
